My sister and I visited Antietam in late November, and saw the repairs going on. Our first day there, we got as close as we could from the west side. Next morning, we approached it from the east side, and saw the Union monuments and the witness tree. The valiant 51st Pennsylvania's monument -- a short, simple little monument with a drum on top -- moved me to tears. Then, as we went back up towards the highway, I detoured into the little clearing in the woods on the hill to see the 11th Connecticut's monument. The story of how its leader, Col. Kingsbury, was killed at the bridge by forces on the other side commanded by his own brother-in-law, Confederate Gen. David Jones, is one of the most heartbreaking of the war. (I first read about it in an excellent historical novel about the battle,
All the Slumberers, which I heartily recommend.) When poor Gen. Jones found out that his forces had killed his brother-in-law, he broke down and was never the same. He resigned from the Confederate Army, went home, and died a few months later of heart failure.
Antietam is, for me, the saddest of battlefields, and the bridge its saddest spot.
